APPARATUS FOR COOKING BY ELECTRICITY.

SPECIFICATION formingpart of Letters Patent No. 475,187, dated May 1'7,1892.

Application filed May 28, 1891. Serial No. 394,412. (No model.)

:o is a specification.

The object of this invention is to provide a simple and convenientapparatus for cooking by electricity in which the heat may be applied,withdrawn, and regulated by simply 5 regulating the electric current.

Figure 1 of the accompanying drawings rcpresents a plan view of thisimproved cooking apparatus in connection with an electric convertor.Fig. 2 represents a side elevation :o thereof.

Similar numerals of reference indicate corresponding parts in thedifferent figures.

The rings 10 and 11, whereof segments only are represented in thedrawings, constitute 5 parts of an electric-current converter, whichneed not be fully illustrated in this case. The ring l is provided witha boss 12 and the ring 11 with a boss 13, which bosses constitute theterminals or opposite poles of the converter. A bracket 20, composed ofcopper or other suitable conductive metal or composition, is attached tothe boss 12 of the ring 10, and a bracket 30, also composed of copper orother suitable vconductive material, is attached to the boss 13 of thering 11. These brackets are provided, respectively, at their outer endswith horizontal arms 21 and 3l, disposed in alignment with each other inthe same plane. These arms are preferably slotp ted longitudinally, asillustrated in Fig. 1. Adjustable clamps 40 and 50 are disposed, relspectively, on the arms 21 and 31, being fastened thereto in anysuitable manner. These clamps comprise, severally, a fixed jaw 41 and amovable jaw 42, hinged to the jaw 41, said jaws being composed ofconductive material, and the hinged jaw being provided with anactuating-lever 43, which is provided with an insulated handle 44 whendesired to be actuated by hand. 5o

A heater GO, having a current resistance greater than that of the clamps4:0 and 50, is supported between said clamps. This heater, as shown inthe drawings, is in the form of a grate composed of iron or steel andprovided 55 with elongated tangs 61 at its opposite ends, which tangsare grasped by the clamps 40 and 50. y

In the use of this apparatus a teapot, pot, kettle, oven, or otherutensil containing the 6o articles to be cooked is placed on the grateG0 and the electric current switched on, said current passing from thering through the bracket and arm 21 to the clamp 40, thence through thegrate GO, which, bein gof greater re- 6 5 sistance, is heated to acherry-red or other suitable temperature. The current then passesthrough the clamp 50, arm 31, and bracket to the negative ring 11. Theheat developed in the grate GO is radiated and conducted there- 7o fromto the cooking utensil resting thereon and to the food contained in saidutensil.

A rheostat may be used for regulating the current and governing the heatdeveloped from the heater.

IVe claim as our invention- In an electric cooking apparatus, thecombination of two converter-rings constituting opposite electric poles,two conductive brackets attached, respectively, to said rings and 8oprovided with horizontal arms, two clamps or holders adjustable on saidarms and provided with clamping-jaws, and a grate supported by saidclamps and serving to close the circuit between them.
